5.3.3Performance Data

All WAN ports gather performance data. The performance data for a T1 line is viewed by typing “p” in the WAN port Main Screen, to invoke the Perf command. Performance data is accumulated for 15-minute increments that include the current period and the previous 96 periods (24 hours), which are accessed via the pgUp and pgDn commands of the Main Screen. Performance data can be viewed for each WAN port by moving to that port and then selecting the “p” option.

In an T1 environment, an error is defined as any CRC-4 error, Controlled Slip, or OOF error.

Figure 5-8shows a typical T1 Performance Data Screen. The performance statistics are gathered and displayed in 15-minute intervals. Lines in each of the columns represent periods when no seconds have accumulated.

In the AT&T mode, two sets of registers accumulate performance data for 4 WAN links. The user registers and network registers are driven by the same errored events. However, they can be cleared separately. You can view both the user and network registers, but you can only clear the user registers. The network only has access to the network registers, and can only clear those registers. The ANSI and T1 WAN links have only one set of registers.

Table 6-3 lists the actions available from the Performance Data Screen.

	must be used to update the screen with new information.
pgUp	Pages through the performance statistics for the current 15 minute period
	and periods 96-1.
pgDn	Pages through the performance statistics for the current 15 minute period
